SPECIFICATION forming part of Letters Patent No. 724,328, dated March 31, 1903.

Application filed Tune 5, 1902. Serial No. 110,313. (No model.)

To all whom it may concern.- I

Be it known that I, MAURICE PIVERT, a citizen of the United States, and a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Mixing-Valve for Explosion-Engines, of which the following is a full, clear, and exact description.

The invention relates to explosion-engines of the four-cycle type; and its object is to provide a new and improved mixing-valve for explosion-engines whereby a perfect mixture of the air and the gasolene or other explosive vapor used is obtained to insure a powerful and regular explosion of the mixture in the working chamber of the engine.

The invention consists of novel features and parts and combinations of the same, as,

A practical embodiment of the invention is4 represented in the accompanying drawings, forming a part lof this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional sidev elevation of the improvements as applied. Fig.2 is a plan view of the regulating feed-valve. Fig. 3 is a sectional plan view of the improvement on the line 3 3 of Fig. l, and Fig. 4 is a similar view of the same on the line 4 4 of Fig. l.

The explosion-engine von which the improved valve is employed maybe of any approved construction-such, for instance, as shown and described in the application for Letters Patent of the United States filed by me under even date herewith; and the engine is provided with a casing A, having a B, as plainly indicated in Fig. l. Opposite.

the valve C is arranged an inwardly-opening exhaust-valve E, normally held on a valveseat B', formed in the bottom of the chamber B and leading to the exhaust-chamber B2. The exhaust-valve E is periodically opened by a suitable mechanism actuated from the main shaft of the engine to allow the prodto their seats F' and D'.

other impurities from passing into the en gine. v The top portion of the interior of the valve-casing F is formed with a conical valveseat F', on which is normally seated a conical valve H, secured on the upper end of a valve-stem I, carrying at its lower end the valve C, mounted to slide in a suitable central bearing D3, extending upwardly from the bottom D2 ofthe plug'D.

A spring J rests at its lower end on the screen G and presses with its upper end against the under side of the conical internal valve H to hold the valves Hand C normally A gasolene-feed channel F2 leads into the apex end of the valve-seat F', and the said channel F2 connects with the apex end ot a conical valveseat F3, into one side of which opens the feedgroove F4, connected with a gasolenesupply pipe K, screwed oar otherwise secured to the valve-casing F.

A conical regulating Yfeed-valve L extends into the seat F2 and has its threaded stem L' screwing in the top of the valve-casing F, and on the outer end of the said stem L is secured a toothed wheel L2, adapted to be taken hold of by the operator to turn the stem L', so asto screw the same inward or outward to bring the valve L nearer to or farther from the valve-seat F2 to regulate the amount of gaso- .lene passing from the feed-groove F4 to the channel F2. A spring N engages the wheel L2,so as to holdfthe valve L against accidental movement. Air-openings F5 are formed in the valve-casing F and lead to the base end of the valve-seat F', as plainly indicated in Fig. l.

ICO

and channel F2 on to the apex end of the said conical valve H, whereby the gasolene is spread and flows downward on the valve and seat, and as at the same time the air is sucked in through the openings F5 it is evident that this incomingair comes immediately in contact with the gasolene, and consequently a thorough mixture of the air and gasolene takes place, and this mixture passes down through the valvecasing F, through the screen G and apertures in the bottom D2, to finally pass through the open valve-seat D' into the chamber B and cylinder of the engine. On the return or compression stroke of the piston the explosive mixture in the cylinder is compressed and finally ignited to send the piston down on the power-stroke, and when the piston returns the valve E is opened to cause exhaust of the products of combustion from the chamber B to the exhaust-chamber B2. On the next downward stroke of the piston the suction period sets in and the above-described operation is then repeated.. When the piston reaches the end of the suction-stroke,the valves C and H move immediately to their seats by the action of the spring J, and the said valves remain closed until the next suction period sets in.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A mixing-valve for explosion-engines, comprising a valve-casing formed with an internal conical valve-seat, afeed-channel leading to the apex end of the seat, 'rh/e said cas` ing having air-inlet openings lefling to the base end ofthe valve-seat, a c nical valve' for engaging the valve-seat, a stem carrying said valve, a second valve carried by the stem and adapted to engage a valve-seat carried by the casing, and a partition having apertures therein leading from the interior of the casing to said valve;seat, as set forth.

2. A mixing-valve for explosion-engines, havingavalve-casin g formed with an internal valve-seat, a gasolene-feed channel leading to the seat at the apex end, air-openings in the walls of the said valve-casing, leading to the base end of the said seat, a plug carrying the valve-casing and having an external valveseat, and two valves vmoving in unison and adapted to be seated on the said seats, as set forth.

\ 3. A mixing-valve for explosion-engines, having a valve-casing formed with an internal valve-seat, a gasolene-feed channel leading to the seat at the apex end, air-openings in the walls of the said valve-casing leading to the base end of the said seat, a plug carrying the valve-casing and having an external valveseat,two valves moving in unison and adapted to be seated on the said seats, and a spring for normally holding the valves to their seats, as set forth.
